AirShutterAdjustment
The burner aeration is factory set, but may need adjustment due to altitude
or the local gas supply.
Air shutters increase or decrease the amount of air mixed with fuel, af-
fecting combustion and how the flame looks. Low primary air will create a
taller, yellower flame, and higher primary air a lower, bluer flame.
Air shutter adjustment is not just for appearance - not enough primary
air may lead to carboning, sooting, or a flame that reaches the top of the
firebox. Units that are burning propane, installed at higher elevations, or
run on high most of the time may need more primary air.
